The bottom half of some symmetrical calculations are shown above. Can you work out the answers?
Can you make up some other calculations where the calculation and the answer both have horizontal lines of symmetry?

[Teacher: pull down the mirror at the top of the screen to show the top halves of the calculations]

Here is an example where the calculation and the answer both have horizontal lines of symmetry:

l00 + l l l + l l + l l l = 333

If you can find any other interesting examples please let us know
here.

Your next challenge is to make an equation with a horizontal and a vertical line of symmetry or a mathematical ambigram

Ambigrams were made famous in Dan Brown's novel "Angels and Demons"

Hello World

You are buying a (driverless) car. One vehicle is programmed to save as many lives as possible in a collision. Another promises to prioritize the lives of its passengers. Which do you choose?

Welcome to the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions – in healthcare, transport, finance, security, what we watch, where we go even who we send to prison. So how much should we rely on them? What kind of future do we want?

Hannah Fry takes us on a tour of the good, the bad and the downright ugly of the algorithms that surround us. In Hello World she lifts the lid on their inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing. more...

Teacher, do your students have
